G Speed

Hello,

Car:
09
Cobalt
Auto
LT
21,000km's

Was driving my gf's car the other night, going about 80-90km/h... when all of a sudden the car jerked?

I'm like wtf was that.. she goes yea that happens once and awhile... I do recall here telling me about something like that before..

Hard to explain it... I drive stick, so I know what a slipping cluth feels like...

It was almost the opposite?

I was going at a constant speed, so I doubt the engine decieded to downshift - then upshift in a matter of a second....

Even if that was the case, I would be accelerating not jerking.. almost like the feeling of a bad a shift where your foot slips of the clutch pedal...

Thanks,

John
